I think I prefer non-lucid. I want to actually believe them while they're happening. And I actually LIKE nightmares, or dangerous situations where I think I'm gonna die, or just uneasy situations like swimming in a river where you are thinking there might be an alligator. Lol. Or even dreams where I fall from a deadly height, although those give me an unpleasant feeling physically. I can't really describe where I feel it in my body though. Maybe my head and chest, like an extreme pressure or something, as soon as I start falling. But I wake up going, THAT WAS COOL!! And the more memorable, the better.
